The jaw plate of the jaw crusher is referred to as the jaw plate, which is divided into a fixed jaw plate and a movable jaw plate. It is a wear-resistant part of the jaw crusher. In the operating state of the jaw crushing equipment, the movable jaw is attached to the movable jaw to perform a compound swing motion, forming an angle with the fixed jaw to squeeze the stone. Therefore, the jaw plate is an easily damaged accessory in the jaw crusher. So what role does it mainly play in the crusher equipment?
The jaw plate is the main wear-resistant part of the jaw crusher, the movable jaw plate and the static jaw plate. According to different models of jaw crushing equipment, there are many models and sizes. The jaw plate is made of new high manganese steel, which is suitable for various specifications of jaw crushing equipment.
The jaw crusher is composed of a working cavity, which is composed of a movable jaw and a fixed jaw. The movable jaw and the fixed jaw bear the huge material squeezing force and friction between the action, which is easy to wear. In order to protect the jaws, wear-resistant liners, also known as crushing plates, are usually installed on the surfaces of the movable and fixed jaws. The surface of the crushing plate is usually made into a tooth shape, and the peak angle of the crushing plate is 90~120, which is determined by the nature and size of the material to be crushed. When crushing large pieces of material, the angle is larger. When crushing small pieces of material, the angle can be smaller. The size of the pitch depends on the particle size of the product. The particle size is usually equal to the width of the discharge port. The ratio of the tooth height to the pitch can be 1/2 to 1/3.
When working, the wear speed of the upper and lower parts of the crushing plate is different, and the lower part wears faster than the upper part. When the jaw crusher is working, the crushing plate is in direct contact with the material, and it bears the huge crushing force and the frictional force of the material. The service life of the crushing plate is directly related to the working efficiency and production cost of the jaw crushing equipment. Therefore, it is particularly important to extend the service life of the crushing plate of the jaw crusher. In order to increase the service life of the crushing plate of the jaw crusher, improvements in the design, material selection, assembly and use process can be considered.
The larger consumption in the production of jaw crusher is the jaw plate, so it is necessary to ensure good quality in the selection of talents. It can also be said that the quality of a crushing equipment is actually based on the service life of the jaws, and the shell of the crusher is generally not easy to damage. Because the objects we need to maintain are clear at a glance.
